The power amplifier board must be connected to AC 220v to be used, and the battery can not be used

Use precautions to avoid burning:
1. It is strictly prohibited to connect the positive and negative poles of the power supply to the opposite, and the opposite will burn, be sure to pay attention.
2. Power connection and overpressure are strictly prohibited

Power amplifier with speaker relay protection, startup delay, shutdown instantaneous break, effectively solve the impact of the switch, the red terminal connected to 110V/220V AC is to supply power to the relay, must be connected, otherwise it will not work, (and the power amplifier part is completely isolated and safe to use); The board is a single DC power supply 12-110V, (different batches of capacitors and other components are about different, please refer to the actual prevail, performance unchanged)

Power amplifier has 1000W and 1500W , the board size are the same, the tube type, capacitance, inductance are differents, according to their own needs to buy,

1000W Support 4-8 OhMs, power supply range DC 12V ~ 90V, 90V 4 OHMs power 1000W, 8 ohms 500W; Size: Length width height 154x73x28mm, weight: 226g

1500W support 4-8 OHM, power supply range DC 12V ~110V, 110V4 OHM power 1500W, 8Ohm 750W; Size: Length width height 154x73x28mm, weight: 260g

The higher the supply voltage, the greater the power, and the smaller the vice versa, and the minimum 12V power supply

Imported MOS tube and Japanese full digital chip design, sound quality and power far supermarket surface TPA3255 and other digital chips, all imported components plus SMT process, excellent workmanship, low distortion, stable and reliable performance

The power amplifier has been repeatedly debugging by engineers for a long time, improved and developed HIFI class D power amplifier board, the whole board is equipped with AVX tantalum capacitor, ELNA blue gown endless audio capacitor, imported high frequency capacitor and other high-end components, the sound is mellow, the bass is elastic
